One object of this invention is to provide a traveling carriage with anovel slip receptacle or chute which may be used alone on the carriageor in conjunction with a card chute or other'types of receptacles suchas illustrated in the parent application above mentioned.

Another object of this invention is to provide normal means on the slipchute for concealing the printing in a particular column of the slip.

. Another object in addition to the concealing means is to provide novelmeans whereby only the printing line of the slip in the chute is exposedto view in other particular columns of said slip.

Another and more specific object of this invention is to provide theslip chute with a hinged member which may be used to conceal theprinting in any desired one of the vertical columns.

showing a portion of a carriage and a platen,

and illustrates the slip chute mounted in position on the carriage.

General description The present invention is incorporatedin a machine ofthe well known Ellis type having a traveling carriage. This invention inthe preferred form includes a slip receptacle mounted upon thetravelingcarriage in such a way that material placed therein is interposedbetween the printing type and the platen roll.

The slip chute has a plurality of compression rolls which hold the slipsinserted therein securely against the platen roll so that such slipswill be automatically fed by said platen roll. Convenient means forreleasing the compression rolls is supplied for use when removing orinserting slips.-

As set forth in the objects the novel slip chute is provided with meansfor concealing the printing in one of the columns when desired, alsowith means for concealing all of the printing in the remaining columnsexcept that on the printing line when desired.

DETAILED Dasciurrron Traveling carriage and platen 7 Only so much of theplaten and traveling carriage have been shown in this case as isnecessary to illustrate the relative location of applicants novel slipreceptacle or chute to the platen and carriage.

A usual platen roll 44 is journaled at one end in arm 39 on a travelingcarriage frame 45 (Fig. 3). The carriage frame 45 is slidably mounted ona machine case 46 which incloses the machine mechanism and is in turnsupported by a machine base (not shown).

Slip receptacle or chute The traveling carriage frame 45 of the presentmachine is equipped with a slip receptacle or chute H8 (Figs. 1, 2, and3) which as previously stated may be used alone or in conjunction with acard chute such as shown in the parent application above referred to. Ia

Fig. 3 well shows the location of the slip chute upon the travelingcarriage and its position in relation to the platen while Figs. 1 and 2illustrate in detail the construction of the slip chute H8. Referring toFig. 1, the slip chute H8 includes a pair of end plates I I3 and H4supported by rods 41 and 48 carried by a pair of carriage end plates 50(only one of which is shown, Fig. 3) which in turn arecarried by theshaft of the platen 44 and travel as a unit with the traveling carriage.Rods H6 and H1 (Figs. 1 and 2) and shafts I20 and m extend the width ofthe slip' chute II8 and connect the plates H3 and H4. A guide plate I22is secured to the rod H6 and is also supported by the rods I I1 and 48.The guide plate I22 is formed around the platen roll 44; ample clearancebeing allowed between the guide plate and platen roll for the insertionof slips therebetween. The guide plate I22 is supported at its front endby projection I23 thereon bent around the rod 41. The guide plate I22has a plurality of openings I24 through which the printing type 38'makescontact with the slip.

Hinged to the rod 41 and straddling one of the projections I23 is acover I25 (Fig. l) which may be used to hide from view matter printed inone of the columns on the slip. Also hinged to the rod 41 between thecover I25 and another of the projections I23 is a cover I26 having aslot I21. When the cover I26 is in place over one of the openings I24only the matter on the printing line is visible through the slot I21.

The shaft I20 (Fig. 1) has secured thereon a pair of adjustable tensioncollars I28 each having a hole into which is inserted one end of a pairof springs I29. The other end of each spring I29 is inserted in a holein each of a pair of tension arms I30. The arms I30 each have securedthereto a hub I 3| by means of which said arms are pivoted on the shaftI20. The hubs I3I are each partly cut away on'their face to form a stepwhich is adapted to cooperate with like steps cutin adjustable releasecollars I32 secured to the shaft I20 for a purpose to be laterdescribed. Pivoted between the arms .130 is a compression roll shaft I33having pivoted thereon a plurality of compression rolls I34 heldinposition by clips I39. A release 'arm I35 secured to the right end ofthe shaft I20 carries a stud I36 which is adapted to cooperate with acam slot I31 in a release lever I38 pivoted on the rod 48.

The shaft I U is similar to the shaft I 20 and carries two tension armsI40 each having a stepped hub I4I, two tension collars I42, two tensionsprings I 43 and two stepped release collars I44. The arms I40, hubsI4I, collars. I42, springs I43 and collars I44 are identical with thearms I30, hubs I3I, collars I28, springs I29 and collars I 32respectively, and therefore, only one of each of the former elements isshown in Fig. 1. The arms I 40 support a shaft I45 carrying tensionrolls I46 held'in place by clips I39. Also secured to the right-end ofthe shaft I2I is a release arm I50 carrying a stud I5I cooperating withcam slot I52 in the release lever I38.

The steps on the hubs .I3I and MI and the steps on the collars I32 andI44 are cut ofi center to allow the arms I30 and I40 to be movedindependently of the collars I32, to the end that when the release leverI38 is in the position shown in Figs. 1 and 2, the rolls I34 and I46under tension of the springs I29 and I43 will be urged toward the platenroll 44 thereby firmly holding the slip inserted between said rolls andplaten so wise, and the arm I 50 and shaft I 2| counterclockwise. Thiscauses the steps on'the collars I32 and I 44 to engage the steps on thehubs I3I and I to rock the rolls I34 and I46.away from the platen roll44.

Let us assume that the present invention is being used on a machine by atelephone company in a large city having a great number of subscribers.The system used by this company. requ res that its subscribers pay afiat rate for a register number.

same as before.

.same as that of the telephone they represent.-

The monthly calculation of each subscriber's account takes place uponawork sheet or slip I81 (Fig. 3) which is arranged to take care of themonthly statement of one hundred subscribers whq are listed numericallyby telephone or register number ina column headed telephone or At afixed time each'montha reading is takenof the telephone registers byphotographing them in blocks of one hundred. Prints of these photographsare turned over to the machine operators forthe purposeof copying theregister readings upon the work sheet which is accomplished thus.

The operator releases the slip chute compression rolls I 34 and I46(Fig. 1) by moving the lever I38 clockwise. The work sheet or slip I81representing, in the illustrative case, the register numbers 3800 to3899 is then inserted in the slip chute, adjusted until the line bearingthe first register number is in line with the printing type and is thenclamped in position by releasing the lever I38. The operator then raisesthe cover I25 which previously obscured the column headed presentreading and copies therein the register reading taken from thephotographic print of the registers 3800 to 3899 inclusive. The machineis arranged to automatically feed the work sheet in the usual mannerfrom line to line near the end of eachoperation.

After having copied all the register readings the operator in a clearingoperation of the machine prints the total thereof at the foot of thepresent reading column. The cover I25 is then closed, the cover I26raised, the work sheet returned to the starting position and thetraveling carriage tabulated until the column headed proof reading'is inhorizontal alinement with the printing type. In this column the operatoragain copies the register readings from the photographic print andtakes. a total thereof,-the This total is compared with the previoustotal for the purpose of detecting errors in the copying of the registerreadings.

When finished with one account the work sheet is automatically turnedupward to the next line bearing the register number 3801.

When the minimum number of calls allowed by this contract has not beenexceeded this fact will be manifest to the operator when the grossnumber of calls is printed in. the gross usage column on the work sheet.

While the form of mechanism herein shown and described is admirablyadapted tofulfill the objects primarily stated, it is to be understoodthat it is'not intended to confine the invention to the one form ofembodiment herein disclosed for it is susceptible of. embodiment invarious forms all coming within the scope of the claims which follow.
